FRANK LUISA AND JAMES DI n' TVEN LABEL CUTTER.

ApplicationI filed March 30, 1925. Serial No. 19,233.

To @Z110/710m z' may con-cera:

Be it known that we, FRANK LUISA and .latins Dr Ma'rrno, citizens of the United States, residing at N ew York, in the county oi' New York and State ot New York, have invented certain 'new and useful lmprove ments in Twin Label Cutters, ot'r which the following is a speciiication.

This invention relates to improvements in label cutters, and it is the principal objectot my invention to provide a label cut for cutting a double. stack of labels from sheets at one operation, and ifor simultaneously removing the waste in order to prevent a clogging ot the cutting machinery thereby.

Another object of the invention is the provision of a label cutter of this character including an adjustable blade,`for removing the waste..

A further object ot the invention is the provision ot' a label cutting machine having a plurality ot delivery chutes for the labels cut from the blank sheets bythe machine.

A still Yfurther object oi the invention is the provision of a'plurality ct adjustable hollow punching devices. y

Other features and advantages of the inven n will become more lully know-n as the description thereorn proceeds, and will then be specifically pointed out in the appended claims.

1n the accompanying drawings 'forming a material part ot' this disclosure:

l l i 'front elev ltion ot a label cutting macl e embodying novel and improved fee-nies according to the present invention.

Fig. 2 is a rear end view thereof.

Fig. 3 is a side elevation `ot the cutting end ot the machine on an enlarged scale.

Fig. 1 is a cross-section on line 41-4 of Fig. 3.

Fig. 5 is a bottom plan view of the cutters and co-operating parts.

Fig. G is a section online G of Fig. 5.

Fig. 7 is a fragmentary sectional detail view oi' an adjustment device.

Fig. 8 is a section on line 8-8 of Fig. 3.

rllhe'macliine vequipped with the novel and improved label cutting mechanism can be or' any suitable construction and including, for instance, the cross-head or plunger 10 to which the hollow dies or knives 11 and 12 are secured by means et the boss-13. A pitman 11 has secured thereto' the plunger 10 and is operated from a crank shalt 15 journaled in bearings 16 and carrying'at vone end a flywheel 17 for regulating the movements ot the crank-shalt. The entire nechanism above described is carried by a. support or body 18.

1n tl e lower face of this body 18, two rallel grooves 19 and 2O are cut in which displaceably arranged blocks 21 and 22 the ends oit' adjusting screws 28 and Q11, .o land extending out of the 'plane of body 18 and bearing there adjusting heads.

To the feces ot blocks 21 and 22, they upper flanges 2f and 28 of the hollow cutter dies, 11 and 12 are secured by means of bolts and nutsl Si() which, in this manner, may be displaced across the body 18 by the proper manipulation ot screws 23. 211, 25 and 26.

A pair ot superposed delivery chutes and 31 are secured to the body 18 at their angnlarly bent ends as at 32 and 83 and lave their bent lower ends .1n communication with the dies 11 and 12.

The guides lor `the labels, during their initial travel, 4in these 'delivery chutes are designated 31and35, and may be adjusted to contorni to the size ot the blades by ad- `iusting screwslG and 37 movable in slots 38 e. fl J oi-plate's L1t) and Z11, attached to guides L) l nd 35. rihechutes are made in two parts yerl.: \ing at their ends and'attached to cn other by means ot screws 412 and 18. 1n order to prevent clogging by waste ma- C) CD35 verial, a waste cutting blade 111 is provided having` the appearance o1 a stretched U in side elevation, the upper ends of the shanks et which are attached to cylindrical blocks 115 and 18 working in casings 417 and 48 ad- 'jnstably secured to thel outer face of body 18.

The casings l17 and 18, have cach lateral flanges 19 and 5) provided with'slots 51 and 52 respectively in which adjusting screws 53 and 51 working, Vengaging with vtheir lower ends in grooves 55 in the oppositely disposed faces of the body 18. The reduced ends of blocks 15 and 16 extend out ot casings 17 and 18 and carry locking nuts 5G and 57 on their upper screw-threaded ends 58.

Springs 59 are wound about the screw parts of 415 and 16 and engage with their upper ends the upper walls of easings L17 and rest with their lower ends in the bottom thereof.

The operation ly understood of the device will be fulroin the above description, the double dies and double delivery chutes will cut and' deliver the double amount of labels as heretofore, and if an adjustment or" these dies is desired this can readily be made by means of the proper manipulation of screws 23, 24, 25 and 26.

The waste accumulating during the cutting operation will be cnt and removed by means of the blade da which is adjustable and cushioned.

lt is to be understood that the device shown and described is an illustration of its4 preferred form only1 and that it can be subjected to any changes such as l'all with* in the stope of the appended claims without departure from the spirit of the invention.

Having thus described our invention, what we claim as new, and desire to secure by laetters Patent, is:

l. Label cutting` and punching machine, comprising a grooved body, a pair of hollow cutting dies, sho-es lor said dies adjustable in the grooves oit said body, means for delivering the cut labels, and a means for removing the waste paper aiiter each operation of the cutting dies.

2. Label cutter, comprising a grooved body, two juxtaposed hollow cutting dies, slices for said dies adapted to be displaced within the grooves of said body, set screws ilor displacing said shoes `for adjusting said dies in their relative positions to said body, a pair of adjustable delivery chutes for the cut labels, and an adjustable waste remover and blade attached to said body between said dies.

3. ln a label cutting and punchingl machine olf the class described including` a body and a pair of hollow, juxtaposed cutting dies adjustably held in said machine, a waste remover blade comprising a pair of cushioned arms or shanlrs adjustably guided on said body and means for locking the parts in their relative adjusted positions.

4. In a label cutting and punching machine of the class described, including a grooved body and a pair of hollow juxtaposed cutting dies, adjustably held in said machine to said body, a waste paper removing blade of substantially stretched U-shape, having upstanding cylindrical shank ends, a chamber receiving said ends, a stein formed with said ends extending through said chamber, locking nuts upon the upper threaded end oi said stem and a spring wound about said stein in said chamber, resting on said cylindrical shank ends and engaging the upper wall ot said chamber, and means for displacing said chamber body within the grooves or' said grooved body and for locking the parts in their adjusted relative positions.

5. In a label cutting and punching machine of the class described, the combination or a grooved body adapted to be secured to a plunger of the machine, a pair of hollow, juxtaposed cutting dies, llanges on said dies, shoes to which said flanges are secured, adapted to slide within the grooves of said body, set screws for holding said dies to said shoes, and set screws for displacing said shoes in said grooves and for holding the parts in their relative adjusted positions, a pair of superposed label delivery chutes, means for allowing an adjustment or' the height or' said chutes, means for attaching said shoes to said body, a` pair of chambered lugs, flanges on said lugs, means for displacing said lugs and for locking them in their adjusted positions in the 'grooves or"V said body, a cushioned waste remover blade entering with itsI shanlrs, said chambered lugs and a means for adjustably securing said 'blade to said chambered lugs.

In testimony whereof we have aliixed our- Signat-rires.

FRANK LUISA. JAMES DI MATTEO.
